Do you need a fresh air vent in your bedroom?

The bedroom is one of the rooms we spend the most time in, around 7-8 hours a day. This also means that a large amount of moisture tends to accumulate in the room, as each person exhales around two liters of fluid per day.

Why is supply air necessary in a bedroom?

Good supply air in the bedroom is important because it ensures good air quality, while contributing to a healthy indoor environment. When you sleep, you consume oxygen that needs to be replenished via the fresh oxygen-rich air from outside.

 

If there is not enough fresh air supplied, the oxygen level in the bedroom can drop. This in turn can lead to fatigue and poor sleep quality. But that's not all, the body also releases moisture through breathing and sweating.

 

This in turn creates good conditions for increased humidity, which can result in mold and musty odors. As if that weren't enough, the lack of supply air can also lead to high levels of carbon dioxide. Some of the side effects are headaches, fatigue and difficulty concentrating.

Recommendations from the Swedish National Board of Housing, Building and Planning

To achieve good ventilation in your bedroom, we recommend installing a fresh air vent, such as one from Airmove . This will help ensure good air quality, while preventing you from breathing in moisture, mold, and other harmful particles.

 

Below is a table with recommended airflows according to the Swedish National Board of Housing, Building and Planning's building regulations (BBR) . If you pay attention, you may notice, for example, that the Swedish National Board of Housing, Building and Planning recommends one vent for every 25m² of living space.

 

Parameter	Recommendation
Outdoor air flow per floor area	At least 0.35 liters per second per square meter of floor area.
Supply air flow per sleeping place	At least 4 liters per second per sleeping place.
Valve per living space	At least 1 valve per 25 m² of living space.
Air exchange in bedrooms	The air in the bedroom should be replaced at least once every two hours.

How to calculate your airflow needs

To calculate how much airflow you need to achieve, we will use simple math. We will also assume that you have a 15 m² bedroom with one sleeping area. Based on the above, we can calculate the airflow as follows:

●      Outdoor air flow : 0.35l/s × 15m2=5.25l/s

●      Supply air flow : At least 4l/s per sleeping place.

This means that a bedroom with a sleeping area of ​​15 m² needs at least an airflow of at least 5.25 l/s to ensure sufficient ventilation in the bedroom.

The air needs to be replaced every two hours.

The Swedish Energy Agency is following the same path and emphasizes the importance of a well-functioning ventilation system. The recommendation is to replace the air in the bedroom every two hours to avoid negative health effects.

Here is a simple graph that illustrates how air quality changes in a bedroom during a typical eight-hour sleep period. The data is based on guidelines from the Swedish Energy Agency and illustrates how carbon dioxide (CO₂), humidity and oxygen levels are affected for each hour you sleep.

High concentration of carbon dioxide

A bedroom that lacks adequate ventilation is at high risk of accumulating carbon dioxide, including a number of other pollutants that are formed while you sleep. The bad air can result in a number of ailments, with headaches, fatigue and poor sleep quality being among the most common.

 

By investing in an affordable fresh air valve, such as Airmove 3.0, you can reduce the negative effects of bad air. Our product has been designed with a function that automatically regulates the airflow based on the prevailing outdoor temperature.

Where should you install a fresh air valve?

Our recommendation is to place your fresh air valve approximately 220-240 cm from the floor and preferably 0.5 meters from the nearest heat source. We do not recommend mounting above windows.
Also remember that air tends to travel the shortest path.

 

This means that the fresh air valve should be placed as far from the door as possible. If you are looking for a cost-effective and flexible solution, the answer is simple. Airmove 3.0

 

The model has been designed with a focus on simplicity and usability. This means, for example, that you do not need to regulate the air flow yourself, the self-adjusting thermostat that does not require electrical installation takes care of opening and closing the valve depending on the outdoor temperature. All incoming air is directed up towards the ceiling where we have a heat barrier to mix it with fresh oxygen to get a better distribution of the air. Airmove 3.0 also has a built-in overpressure protection that closes the valve to avoid cross drafts in cases where you open a window or door to ventilate. This option is ideal if you want total control over your ventilation.

Improve ventilation in your bedroom

If your house doesn't have access to a mechanical ventilation system, you most likely have something called "self-draft." When it comes to houses with self-draft, the rule of thumb is to let fresh air from outside into all rooms - except the kitchen and bathroom.

 

When it comes to the bedroom, it is crucial to have a fresh air valve installed to ensure the supply of air from outside. For the valve to function optimally, the old air needs to be led out of the bedroom.

 

This can be achieved by installing exhaust ducts. If this is not possible, it is important to have openings that interact with, for example, bathroom and kitchen fans, or other ventilation solutions that support natural draft.
